(2) \(\frac{(p-q)}{q} > \frac{(p-q)}{p}\)


Statement 1: Both \(p\) & \(q\) are either positive or negative. if \(p=2\) & \(q=1\), then we have \(p>q\) & \(\frac{p}{q}>1\), but if \(p=-2\) & \(q=-1\), then \(\frac{p}{q}>1\) but \(p<q\). Hence Insufficient

Statement 2: \(\frac{p-q}{q}-\frac{p-q}{p}>0 =>\frac{(p-q)^2}{pq}>0\)

Now \((p-q)^2>0\), hence \(pq>0\). This implies both \(p\) & \(q\) are either positive or negative. Same as Statement 1. Insufficient

Combining 1 & 2: We know either \(p\) & \(q\) are positive or negative but we cannot determine the value of \(p\) & \(q\). Hence Insufficient

Option E

Easy E.

Plug in the numbers -3 and -2 for both the statements. Both statements together are not sufficient to answer the question.

Neither of the statements gives us any information about the sign of p and q. Both the statements are insufficient to answer.

Answer should be E
